To Ann WHoM rr MAY .ooNoEnrn .Be it known that I, BENJMIN 1. LAMAsoN, of Milton, inthe county of Northumberland, and in the Stato of Pennsylvania, have invented a Inew andus'eful Improvement on Caps or Lids for Railroad-CarBozres and I do herab)T declare that t'ho following is a. full, clear, and exact description'of the construction and operation of the some, reference being had'to the annexed drawings,` nialzingo part of these specifications, in which;

'Figure 1 is a front vieu' of cup showing form, I l- Y Figure 2, n transverse section through a a, shoxving hook or clamp b and stop j. Figure 3 is a longitudinal section through b'b, showing cap A and enr-boX-B, the mode Vof attaching Vthe cap to box, and clsothe operation of -hook or clamp b. I" i Y Figure 4 representsa port of clar-box, with a portion of cnp` showing the position of capl when .properly adjusted.

To enable others skilled in the art to make and use my invention, I'ivill proceed to describe tseonstruction I construct my cap in the form of an elliptic, of cast iron, brass, or any like metal. VI make a hole `in one end of cap a, iig. 1, and on the other end I construct a hook or clamp, Vb, gs. 2,3, and 4. This hooker clamp b is so constructed and arrangedl as to it around the box-ear d, figs. 3 and 4. The cnr-box being constructed of the usual form, the cap A is secured to car-box B by means of thel bolt or'sereivc, passing through the cap :it the hole a, and screwed into the box-ear d, thus forming a secure and cilcient attachment. Thebolt c also forms a pivot, on which the cap A revolves. The otherend of. cap is secured hy means of the hook orclampb passing around and beek of box-car d, shown at e, iig. 3. This simple device, itvwill be readily seen, forms a secure fastening when ccp is in place. v

I operato the cap by menus of the hands, the one end of cap being permanently secured to box.- vbythe bolt c. The -other e'nd on which hooker clamp b isconstructed.is left free, and enube raised up or liznvvoere'dl down, as the desire may be, to open or close the hex.4 The stop'f, fig. l2, is designed to preventeap fromY drop.

ping too low when cap is closed. v

Theadvnntages claimed for my i'mprovementare, first, it obvintcs` the necessity o f using more than Vone boltgfcond, ie readily applied,to new -or old car-boxes, and is easily operated, no tool. orv instrunient being 'neccenary; "tlxiid, it is permanently secured to cnnbox, thus preventing theloss of cap nndbolts, Y

Wlint e'inin as my invention, anddesire to secure 'by Letters Patent, is# l The car-axle box lidAprovided with the clamp vb, in combination with theear apolied'to the car-aille hox.
